` To all 'whom z5 may concern:

sota, have invented certain new and usefuly improvements in Mop-lVringer Pails; and

- we doliereby declare the yfollowing to be la full, clear, and exactdescription of the iiivention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to provide an extremely simple and highly etticient mop wringer pail; and, to such ends, generally stated, the invention consists of the novel 'devices and combinations of devices hereinafter described andpdened inV the claims. Y

In the accompanying drawings, which illustrate the invention, like characters `indicate like parts Referring tothe drawings, Y Fig. 1 is a sideelevation of the improved pail;

F ig. 8 is a vertical section on the lin 3-3 of Fig. 2; Y

Fig. 4 is a transverse section on the line L -1 of Fig. 2, some parts being removed; and

Fig. 5 is a fragmentary vertical section on the line 5-5 of Fig. 2.

The pail, which is preferably of sheet metal structure, is indicated by the numeral 6. As a supporting' means for the relatively fixed member and pair of wringer4 rollers,

a marginal bearing frame 7 is iitted'withiii and detachably secured to the upper portion of the pail. This frame 7 has parallel sides and segmental ends, the segmental ends iitting within the pail. The segmental* portion of the frame 7, that is at lthe front of the pail, is hung upon stirrup straps 8, the upper ends of which are bent around the end of the pail andthe lower ends of which are upturned to affordseats to receive 'said frame 7. At the back of the pail, the segmental portion of the frame 7 is 'detachably' secured to the pail by a short nut-equipped bolt 9. Vhen the bolt 9 is removed, the frame 7 can be lifted from position, but when the said bolt 9 is applied, said frame throughout theV several- Fig. 2 is a plan view thereof; y 5

is rigidly secured to the pail. When the said frame is applied to the pail, it not only affords a bearing for the fixed roller, but stiifens the pail. Sheet metal plates 10 are riveted or otherwise rigidly secured to the parallelsides of the frame 7 and verticaly roller-supporting pedestals, shown as in the forni of flat metal straps '11 are rigidly secured to the said plates 10 and to the parailel sides ofthe frame 7. Y

The relatively fixed wringer roller 12 is journaled to the pedestals 11. As preferably constructed, said roller 12 is formed Vwith metal caps 13 having trunnions 14 that are directly journaled in the said pedestals 11.

The movable wringer roller 15l isr consid era-bly longer than the fixed roller 12 and, in fact, is as long as thediam'eter of the pail and, like the roller 12, is provided with metal "end caps 1G terminating in trunnions 17. rl`lie trunnions 17 arefjournaled,`each in the upper ends of two link-acting metal arms 18 and 19, flat metal straps.

A. bail-like treadle lever 2O embraces the sides of the pail and its ends, vand the lower ends of the arms 18 are independently pivoted at points offset from each other to trunnion-equipped reinforcing plates 21. The arms 19, at their lower ends, are vpivotally connected tothe lower portions of ,thesides' of the treadle lever 20. One orinore 'coiled springs l22- operate normally to raise the treadle lever 20 and retract' the 'wringer roller 15 from the wringer roller 12; and, asA

that the mop cloth may be freely passedv between the rollers. ,In the wringing action, the mopV cloth, 'by pulling upward on the cloth, will be pulled` upward on the rollers,

while the rollers are forced toward each' other approximately yas shown in Fig; 3.

The squeezing action' of the rollers is,rof

preferably in the form vof l will stand, yas shown in Figs'l and 2, so v,

course, procured by stepping` on the treadle lever 20. lnl the-downward action, produced` by stepping on the treadle lever 20, the .movable wringer roller 15 will move on the arc of a circle struck from the axis on the pivotal connection between the arm 18 and the plate 21 and this movement will be imparted through the arms or link-acting` members 19. The treadle lever 2O and the roller-supporting arms 18 do nota therefore, act as a bell crank lever, but the two are capable ot different movements, each on its own pivot and the squeezing` :torce is `taken in tension through the arms or links 19. This gives a very strong construction with a minimum oit' metal and, moreovera there is produced a sort of a toggle action between the treadle lever 2O and arms or links 19, which gives great squeezing` power. The construction described is also very cheap to make, as well as strong, durable and efficient. The wringer rollers, with their metallic end caps set in flush with the bodies ot the rollers, give very great strength and durability to the rollers and prevent cracking ot the rollers under expansion and contraction, due to frequent wetting and drying.

Plates 10 afford mop retaining guides which prevent the mop `from spreading beyond or, in fact, as tar outward as the ends ot the short roller 12j and, of course., the ends oi the long` roller 15 are tar beyond said guides, so that there is no possibilit-y of the mop becoming wrapped around the trunnions of the rollers. The long rollers are brought outside of the pail so that the links 18 and 19, pivoted to the sides ot' the pail and to the bail 20, may be straight flat members.0

lt is importantto note, (see Fig. 1) that the pivotal connections between the treadle 20 and the bearing` plate 21, are at points that are always between the diverging lines of the copper-ating' links 18 and 19 or, otherwise stated, the pivots of the treadle are in Vthe angle represented by the diverging` links 18 and 19, regardless of the position oi" the treadle. This gives such distance between the lower pivots of the links 18 and 19 that the treadle is given great power because the said parts never closely approximate dead center and never pass from one side to the other ot the dead centers. This arrangement alsopermits the div/erging links torbe ot approximately the same length and permits the links 18 to be pivot-ed approximately on the level with the pivotal connection between the bail and the pail.

`What we claim. is Y 1. The combination with a mop pail and a stationary squeezing roller supported thereabove, of a co-operating movable momes .squeezing roller, a bail having,- straight ends forming a treadleand having its ends pivoted to the exterior sides ofthe pail,V and a pair of'straight links kat each exterior side of the pail having` their upper ends pivoted to the end of the movable roller, one of the links of each pair having; its end pivoted to the treadle and the other link of each pair having its end pivoted to the exterior of the pail adjacent to the pivotal f point oi" the treadle so that said pivotal point ofthe treadle is always in the angle of divergence otsaid links whereby a dead center position is avoided.

2. The combination with a mop pail., of aV marginal supporting-frame having'parallel sides and segmental ends iitting within the rim of the pail, stirrups hung on the rim ot the pail and supporting one of the segmental ends of said trame, means for securing the other segmental end oi' said frame to the pail, fixed bearings on the sides of said iframe, a wringer roller journaled to said lined bearings, laterally 'spaced arms and a bail-like treadle lever ypivoted to opposite sides of the pail at different points, and links connecting the sides of the treadle lever to said arms.

3. A device of the class described having' `in combination a pail, a lined roller journaled above the sainej a movable roller above the pail adapted to move to and from the fined roller, said. movable roller having its ends j ournaled in two links at each side thereoi'.,v one each of which is pivoted at its other end to the side ol' the pail, a bail having' its ends pivoted to the pail adjacent the ends of said last mentioned links and in the same horizontal plane therewith and extend-y ing upwardly and away from said pail, the lower end oit' the other links which are journaled to the movable roller being connected to the sides of the bail above its pivot.

4t. In a mop wringer pail device compris ing a pail and lined and movable rollers supported thereabove, a support for the lined roller comprising an endless trame having parallel rside portions and segmental end portions, the latter fitting' the interior ol' the pail adjacent its top and forming a brace therefor, angle plates secured to the parallel side portions of said frame andhaving' one side extending inwardly therebetween,` and means supporting said members from the upperedges of said pail.

In testimony whereof we aiiiX our signa tures in presence ot two witnesses.
